It looks very creepy. Not to sound all woo-woo, but I wonder whether the energy in some of these old places ever gives you the chills? On a more scientific note, do you worry about mildew and mold affecting the air that you breathe? Honestly, since you are not there that long, it should not be too bad, really. I just worry. Also, I sometimes get creeped out in old places, especially old mental hospitals where you know people probably really suffered since we don't have a great historical track record of being kind to the mentally ill.
I was the casting assistant for a motion picture once that was set in an old mental hospital here. Our buildings are very young by comparison since this province (Alberta, Canada) was only founded in 1905. It gave me the creeps anyhow!
I have am about as receptive to the underworld as red brick. It's an asset in the game I suppose. I rarely feel anything at all. Coming up is a visit to some flats where a murder occurred.. again nothing! Even standing in the very room.
That's very good. I don't even know whether I believe in the "underworld," as you put it, but I still get weird feelings in older places. My scientific mind chalks it up to residual energy, whatever that means. Maybe (probably?) it is just an overly vivid imagination on my part?
